对象数组的多级排序- javascript

var data = [
  { name: "John", age: 25, score: 80 },
  { name: "Alice", age: 30, score: 90 },
  { name: "Bob", age: 20, score: 70 }
];

data.sort(function(a, b) {
  if (a.age === b.age) {
    return a.score - b.score; // 先按照分数升序排序
  } else {
    return a.age - b.age; // 再按照年龄升序排序
  }
});

[
  { name: "Bob", age: 20, score: 70 },
  { name: "John", age: 25, score: 80 },
  { name: "Alice", age: 30, score: 90 }
]
